The single-ended current output of the HA-2557 has a 130MHz signal bandwidth (RL = 50). High bandwidth and low distortion make this part an ideal component in video systems.
The suitability for precision video applications is demonstrated further by low multiplication error (1.5%), low feedthrough (-50dB), and differential inputs with low bias currents (8A). The HA-2557 is also well suited for mixer circuits as well as AGC applications for sonar, radar, and medical imaging equipment.
The current output of the HA-2557 allows it to achieve higher bandwidths than voltage output multipliers. Full scale output current is trimmed to 1.6mA. An internal 2500 feedback resistor is also provided to accurately convert the current, if desired, to a full scale output voltage of ±4V. It is not limited to multiplication applications only; frequency doubling and power detection are also possible.
